具体实施方式 detailed description

[0015]以前的电光调制器包括波导部分和导线部分,其中波导部分传播光信号,导线部分传播射频(RF)信号。 [0015] The electro-optic modulator comprises a previous waveguide portion and a conductor portion, wherein the waveguide portion of the optical signal propagation, propagation wire portion frequency (RF) signal. RF信号与光信号的交互被用于调制光信号。 Interacting the optical signal with an RF signal is used to modulate an optical signal. 尽管设备被倾向设计为光信号和RF信号基本以相似的速度传播,电光调制器的材质和构造可能影响光信号的和RF 信号相对传播速度。 While the apparatus tends to be designed substantially similar propagation speed of the optical and RF signals, materials and construction of the electro-optic modulator may affect the optical signals and RF signals relative propagation velocity. 如果,例如,在电光设备的交互区域中RF信号的传播速度与光信号的传播速度不匹配,调制器的带宽可能会被减少,这种减少显然是不期望的。 If, for example, an electro-optical device in the interaction area does not match the speed of propagation of the optical signal propagation velocity of the RF signal, the bandwidth of the modulator can be reduced, this reduction is clearly undesirable.

[0016] 在此描述的图示的示例性实施例提供了一种方法和系统用于使得在电光设备的交互区域中RF信号的传播速度与光信号的传播速度匹配。 [0016] The exemplary embodiment illustrated exemplary embodiment described herein provides such a method and system for propagating the optical signal velocity propagation velocity of the RF signal in the interaction region of the electro-optical matching device. 这种信号速度的匹配(或调谐)可以增加电光设备和系统的有效带宽。 This signal speed matching (or tuning) can increase the effective bandwidth of the electro-optical devices and systems.

[0017] 图1示出了电光调制器设备100的示例性实施例的部分的俯视图。 [0017] FIG. 1 shows a top view of a portion of an exemplary embodiment of the electro-optic modulator device 100. 在此实施例中, 设备100布置在衬底上。 Embodiment, the device 100 is disposed on the substrate in this embodiment. 该衬底例如为硅衬底材料。 The substrate such as a silicon substrate material. 波导部分102布置在衬底上。 Waveguide section 102 disposed on the substrate. 导线104布置在波导部分102之上的层或者与波导部分102相邻的层。 Lead 104 is disposed over the portion 102 of the waveguide layer or the waveguide portion 102 adjacent layers. 波导部分102被用于传播一个连续波(CW)光输入信号,导线104被用于传播RF输入信号。 For propagating the waveguide section 102 is a continuous wave (CW) optical input signal, the lead 104 is used to propagate the RF input signal. 波导部分102和导线104在交互区域106重叠。 Waveguide portion 102 and the wiring 104 overlap in the interaction region 106. RF信号和波导部分1〇2在交互区域106中的交互影响CW光输入光的调制,由此得到调制的或者编码的光输出信号。 RF signal and the portion of the waveguide 1〇2 interaction region 106 in the interactive effect of the CW input light modulated light, thereby obtaining a modulated optical output signal or encoded. 如上面所讨论的,设备100的构造和材质会影响光和RF信号的传播速度。 As discussed above, the material and configuration of the device 100 will affect the light propagation velocity of the RF signal. 在图示的示例性实施例中RF信号的传播速度会高于光信号的传播速度。 In the exemplary embodiment illustrated in the propagation velocity of the RF signal propagation speed higher than the optical signal. 因此, 降低RF信号的传播速度将会减少光信号和RF信号之间传播速度的相对差。 Therefore, reducing the speed of propagation of the RF signal will reduce the relative difference in propagation velocity between the optical and RF signals.

[0018] RF信号的群速度是线路电感和导线104的电容的函数。 [0018] The group velocity of the RF signal is a function of the capacitance and inductance of wiring harness 104. 改变导线104的电容或者电感将会改变RF信号的群速度。 Changing capacitance or inductance lead 104 will change the group velocity of the RF signal. 图示的实施例包括多个调整部分108,其跨过或者临近导线104。 Illustrated embodiment comprises a plurality of adjusting portions 108, 104 extending across or near the wire. 调整部分1〇8与导线104电绝缘,并且调整部分1〇8例如可以被布置在衬底上的材料的层上,衬底与导线电绝缘。 1〇8 adjusting section 104 and the insulated electrical conductor, and may be, for example, adjusting section 1〇8 layer disposed on the substrate material, the substrate and electrically insulated from the wires. 每个调整部分108都通过一个或多个开关设备110与地相连,开关设备110可以由下面描述的控制器控制。 Each adjusting section 108 through one or more switching devices 110 connected to the ground, the switching device 110 may be described by the following controller. 当某个调整部分108的开关设备110闭合时(也就是说调整部分108在任一端、调整部分108的相对的端或者开关设备110布置在调整部分1〇8的中间区域接地),关联的导线104的电容会增加。 110 is closed when a switching device 108 adjusting section (adjusting section 108 that is at either end, the opposite end adjusting portion 108 or the switching device 110 is disposed in the middle region of the adjustment of the ground portion 1〇8), the wire 104 associated capacitance increases. 导线104的电容的增加会降低RF信号在导线104中的传播速度。 The wire 104 to increase capacitance decreases propagation velocity of the RF signal in the conductor 104.

[0019] 虽然图示的实施例包括2个调整部分位于并关联于每个导线104,替代实施例中每个导线104可以对应任意数量的调整部分1〇8。 [0019] Although the illustrated embodiment comprises two adjusting portion is positioned and associated with each lead 104, an alternative embodiment each wire 104 may correspond to any number 1〇8 adjusting section. 每个调整部分108可以被独立地控制以便可以通过影响将特定调整部分108接地的开关设备110来逐步增加导线1〇4的有效电容。 Each adjustment portion 108 may be independently controlled so that the influence by the effective capacitance 110 to gradually increase the wire 1〇4 specific adjustment portion 108 of the grounding switching device. 通过改变调整部分108的状态(也就是说将调整部分108连接到地的开关设备110的状态),导线104的有效电容可以被增加或者减少以影响RF信号的速度来接近或者基本匹配光信号的速度。 By changing the state of the adjustment portion 108 (that is to say the adjustment portion 108 is connected to the ground state of the switching device 110), the effective capacitance of the lead 104 may be increased or decreased at a rate close to RF signal to an optical signal or substantially match speed.

[0020] 图2示出了导线104和调整部分1〇8的示例性实施例的俯视图。 [0020] Figure 2 shows a top view of the wire 104 and exemplary embodiments of 1〇8 adjusting section. 线负载元件包括与开关设备110连接的传导部分2〇2。 The load element comprises a conductive wire connected to the switch device 110 2〇2 portion. 通过闭合位于调整部分108—端的开关设备110,每个传导部分2〇2可以选择性的、独立的接地。 By closing adjustment portion located side switching devices 108- 110, each of the conductive portions may be selectively 2〇2, separate ground. 开关设备110由控制器部分204控制,该控制器部分204可以被用于输出改变开关设备110状态的信号。 The switching section 204 is controlled by the device 110 a controller 204 may be part of an output signal 110 to change the state of the switching device. 控制器部分204可以包括例如处理器或者逻辑电路,其用于接收输入、处理输入并输出信号。 The controller portion 204 may comprise, for example, a processor or a logic circuit, for receiving an input, the input and output signal processing. 在图示实施例中,控制器204可以闭合开关设备ll〇a〇开关设备110a将传导部分202a连接到地。 In the illustrated embodiment, the controller 204 may close the switch device switching device 110a ll〇a〇 the conductive portion 202a is connected to ground. 这样的连接可以使得导线104的电容增加。 Such a connection may lead 104 such that the capacitance increases. 正如上面所讨论的,导线104的电容的增加会减少RF输入信号的速度(减少RF输入和光信号之间的相对差)。 As discussed above, the capacitance of the lead 104 will increase the RF input signal to reduce the speed (reduce the relative difference between the optical and RF input signal). 如果RF输入的速度的减少是有利的,控制器可以例如闭合开关设备110b以将传导部分202b连接到地,这样会进一步的增加导线1〇4的电容。 If the speed of reduction of the RF input is advantageous, for example, the controller may close the switch device 110b to the conductive portion 202b connected to ground, this will further increase the capacitance of the wire 1〇4. 如果需要,可以通过闭合其他调整部分108的开关设备110来进一步增加电容。 If desired, by closing the switching device 110 other adjusting portion 108 to further increase the capacitance.

[0021]图3示出了调整部分108的示例性实施例的一侧的部分剖视图。 [0021] FIG. 3 shows a cross-sectional view of one side portion of an exemplary embodiment of the adjustment portion 108. 传导部分202连接到开关设备110。 Conducting portion 202 is connected to the switching device 110. 在图示实施例中,开关设备110包括一个或多个晶体管。 In the illustrated embodiment, the switch device 110 comprises one or more transistors. 开关设备110将节点302和控制器2〇4连接到地。 The switching device 110 and the controller 2〇4 node 302 is connected to ground. 调整部分108被布置在绝缘层303中,例如布置在衬底301上的氧化或者氮化材料中。 Adjustment portion 108 is disposed on the insulating layer 303, such as a nitride or oxide material disposed on the substrate 301. 导线104布置在绝缘层303上。 Lead 104 is disposed on the insulating layer 303. 虽然图示实施例包括衬底301和绝缘层303,设备也可以包括任意数量的、包括任意材料的层。 Although the illustrated embodiment includes a substrate 301 and an insulating layer 303, the device may also include a layer of any material comprises any number. 虽然仅示出了一个开关设备11〇,替代实施例可以包括两个或更多的开关设备110,这样传导部分202的每一端都通过开关设备110连接到地,或者替代实施例可以包括在传导部分202的中间区域的开关设备110,其使得当开关设备110闭合时,在传导部分22端部中间有到地的路径。 Although only one switching device 11〇, alternative embodiments may include two or more switching devices 110, so that each end of the conductive portion 202 are connected to ground via the switching device 110, or in alternative embodiments may comprise a conductive the switching device 110 of the portion 202 of the intermediate region, such that, when switch 110 is closed the device, there is a path to ground conductive portion intermediate the ends 22.
